Rails

My friend Robert Nishimura’s looking for a Rails developer for his company, ClearFit, which is based in uptown Toronto. He sent me some details about the position he’s trying to fill; I’ve posted them below.

If you’ve got the skills and if the position sounds interesting to you, you should drop him a line at robert@clearfit.com!

Company Information

ClearFit is changing the way small businesses hire. Most people know that ‘fit’ is the most desirable attribute for employees and employers — that intangible sense that can’t be found in a resume and is difficult to glean from a job interview. It’s a huge problem — employers spend billions every year on staffing in Canada alone.

Most small business owners don’t know where to even start when hiring a new employee. Ask around for referrals, “pay and pray” with a job board or deal with an avalanche of resumes from Craigslist?

We have built the system that some describe as “an eHarmony for jobs”. We have over 2500 registered employers and tens of thousands of registered career seekers which barely scratches the surface of a multi-billion dollar market. All this and we just completed our first round of investment so we are poised for stellar growth.

We are located in the Yonge/Eglinton neighbourhood, strategically situated between 3 Starbucks and 3 minutes from Bulldog Coffee. We’re also upstairs from Copacabana Brazilian BBQ.

Skills & Requirements

Skills:

Minimum 2 years experience coding in Ruby on Rails

Minimum 2 years experience with HTML/CSS

Experience with Javascript (Prototype, JQuery)

Experience with Postgres SQL

Experience with Ubuntu/Nginx

Experience with GitHub

Bonus points:

Experience with Amazon EC2

Experience integrating with other web apps

Photoshop and front-end web development skillz

iOS development experience

What ClearFit Offers

Salary between $80K and $100K based on experience

Welcome to another Salmagundi — a selection of some interesting techie stuff on the web!

In his article Your Code is My Hell, all-round Ruby/Rails guru Avdi Grimm warns Ruby and Rails developers about a creeping exceptionalism that has been rearing its ugly head as of late. Many Ruby/Rails developers seem to be under the impression that simply because Ruby and Rails do a lot to make programming easier, they can simply ignore things like good coding, good object design, design patterns and the SOLID principles and all those other practices and disciplines that good coders follow and exercise. Ruby’s a great programming language and Rails is a great web development framework (and I’m quite glad to return to them), but they’re not a free pass to code carelessly!

Here’s another one from Avdi Grimm (he’s got lots of good suggestions — you should check his blog regularly if you’re a Ruby/Rails developer): The Procedure/Function Block Convention in Ruby. He’s got a clever idea for when to use “curly bracket” blocks (he suggests to use the for functional blocks) and when to use “do…end” blocks (he says to use them for procedural ones.

After three years away from all but the most trivial of noodling with the Ruby programming language, I have become a Ruby Foo (as in Mr. T’s catchphrase, “I pity the foo’!”). I am severely out of practice with Ruby, and with two versions having appeared since I last made a living with Rails, even the act of creating a new project is completely different. Since Ruby is the preferred back-end programming language at Shopify and I am the Platform Evangelist, it’s time for me to “sharpen the saw”.

“I’ve been away from Ruby long enough that I’m probably back at newbie level again,” I told Obie between sips of latte made with overcooked beans. “I did it for a bit at the beginning using IronRuby, but between doing all the C# and PHP and the open source ‘Iron’ languages dying of neglect at Microsoft, I’m severely out of practice. I thinking of joining Shopify, and let’s face it: I don’t want to look like an ignoramus in the presence of rock stars like Tobi, Cody and Edward.”

“Give me your email,” said Obie, “and I can do something to help.” Of course he could – he’s the series editor of Addison-Wesley’s Professional Ruby series of books.

Shortly after South by Southwest, a couple of links to PDF editions appeared in my inbox. Thanks, Obie!

The first link was to Eloquent Ruby, Russ Olsen’s guide to speaking idiomatic Ruby and getting the most out of the Ruby programming language. It’s a breezy read, written in the same conversational tone that Olsen used in Design Patterns in Ruby, and the book is broken down into 31 bite-size chapters about a dozen pages in length. Each chapter’s title is some principle for programming eloquent Ruby – the first few are “Write Code That Looks Like Ruby”, “Choose the Right Control Structure” and “Take Advantage of Ruby’s Smart Collections” – and each explains that principle, provides code, shows you where you can find the principles used in actual, working projects. The book straddles the line between tutorial and reference; it’s written in tutorial style, but it’s organized so well that it might as well be a reference for those parts of Ruby that you might not use often (but should) as well as for those parts you keep forgetting (in my case, I always end up having to look up metaprogramming). I’ve been going through it at about a chapter an evening, and I’ve been getting smarter each time. Whether you’re coming back to Ruby after a hiatus like I am or if you just simply want to get better at Ruby, you should have this book in your library.

I’ll be writing from time to time about my return to Ruby and Rails in this “Ruby Foo” series of posts, and I hope that whether you’re new to the language, returning after a break like me or aiming for “guru” status, that you’ll check out this blog regularly for notes on my explorations and what I’ve learned.

It’s fashionable, or perhaps inevitable, for tech communities to trash their competition…We geeks make arguing over minor technical points into a kind of art.

The most important point in his essay is a few paragraphs down. He points out that while having a competitor often lends focus to a developer community and that a rivalry can often bring about excellence among all parties concerned, it can also bring bitterness and nastiness. He wants to counter those latter things, and so he writes:

I think it’s important to recognize that we in the web development community do in fact owe Rails and the Rails community a debt of gratitude. Rails helped reframe the way we think about web development, and even those who’ve never touched Rails nevertheless are probably reaping indirect benefits right now.

So I think we should all step back from our personal preferences and plainly say thank you, Rails, for all that you’ve done to move the state of web development forward.

Rails was a wake-up call to the web development world in so many ways. In the short time – a mere five years — that it’s been around, it’s been responsible for many changes in the world of web applications:

Popularizing MVC amongst web developers. Yes, it had been done before, but never quite as elegantly or explained so clearly.

Driving a movement towards web applications with both beautiful and usable interfaces.

Reminding us that programming should be fun.

Reinforcing an important idea that we often forget: community matters. (If you’ve been to a RailsConf or better still, RubyFringe and FutureRuby, which takes the Ruby/Rails community camaraderie and turns the dials up to 11, you know what I mean.)

Speaking as a Microsoft guy, I too would like to say “Thank you, Rails”. While I can’t honestly classify myself as ever having been a serious Rails developer – it’s mostly noodling on personal projects and one major cancelled project at Toronto’s worst-run startup – I come from the periphery of the Rails community, having been an unofficial evangelist and occasional court jester, as evidenced in this performance from the evening keynotes at RailsConf 2007:

I take a lot of what I’ve learned from the community-building effort that made Rails what it is today and have applied it to my work at Microsoft. From what I’ve been hearing, it seems to be helping.

It’s not just the community aspects of Rails for which both Microsoft and I owe Rails a debt of gratitude — there are the technical aspects as well. I’m sure the event-driven desktop-style development metaphor behind ASP.NET makes a lot of developers happy, but it drove me bonkers – and also to PHP (and eventually, Rails) — back in 2002. The drive to create an MVC web application framework that treated the web like a first-class citizen instead of “like the desktop, but lamer” led to the creation of my preferred Microsoft web framework, ASP.NET MVC, and I cannot begin to convey how grateful I am for that. I love ASP.NET MVC, and a good chunk of the reasons why stem from the Rails-isms that found their way into it. I think ASP.NET MVC developers would benefit from getting to know Rails and taking it out for a spin – and I think the Rails developers would also gain something from giving ASP.NET MVC a try.

I once read a saying that has stuck with me all these years: “When you slice a blade of grass, you shake the universe.” Yeah, it’s a pretty drama-queeny way of saying that everything is interconnected, but it’s true in many respects, including human endeavour, which in turn includes software development. It’s an ecosystem, and different parts of it influence each other all the time. I think that the best participants in that ecosystem learn from other parts, and acknowledge those efforts that make the ecosystem a better place in which to live.

Introducing LearnHub

LearnHub’s home page.

If you’re a student applying to colleges and universities and are looking for help with the process, you should try LearnHub. Based in Toronto, LearnHub is a social learning network that helps students to prepare for standardized tests, assists with finding places to study abroad and provides career counseling. LearnHub’s site has hundreds of thousands of pages of free content, including the world’s largest bank of questions that appear in the GMAT and SAT standardized tests. The site has a large following among students worldwide, particularly in India, and has partnerships with 25 universities to recruit domestic and international students.

With those hundreds of thousands of pages, LearnHub needed to provide a way for students to find what they’re looking for. They provide a search function, and it’s powered by Bing.

The people at LearnHub are part of that sector of Toronto tech that’s into Ruby on Rails, open source and founding startups. Founders John Philip Green and Malgosia Green are a husband-and-wife team who are known for building web applications for education and have been active members of Toronto’s tightly-knit open source tech community since the earliest DemoCamps. John caught Rails fever after trying it out and decided to rewrite a major application using it. The core development team of Wesley Moxam, Carsten Nielsen and Libin Pan are fixtures of the local Toronto’s on Rails scene; a gathering of local Rubyists doesn’t feel complete without them.

So what are they doing, using Bing?

Site-Wide Search

The main room at LearnHub’s offices. Management are to the left, developers to the right.

In the beginning, they went with their first instinct, which was to use Google. “We launched in March 2008,” said co-founder John Philip Green, “and we needed to provide site-wide search, so we went with Google. We signed up, and for a few hundred bucks a year, we got a search function that covered about 5,000 pages. It seemed like a pretty big number, and we thought that would be more than enough to cover our site.”

They soon found that the results weren’t what they expected. “We weren’t getting good results. We’d use our site-wide search to search for something that we knew was in our site, and it wouldn’t show up in the results.” The same search would work just fine if you did it from Google.com, but not from their Google-powered search function. “The results just weren’t relevant, and we also had a limited number of queries,” John said.

The main room at LearnHub’s offices. That’s management in the foreground, developers in the back.

LearnHub’s page count grew quickly and beyond the 5,000 pages covered by their arrangement with Google. “Going up to a bigger package was expensive;” John said, “it would have cost a couple thousand for 50,000 pages, and we were already at hundreds of thousands.”

“We could’ve gotten the functionality for free, but that’s only an option when you show ads in the search results, and the ads that showed up were for our competitors.”

LearnHub’s sales team.

There was another problem: Google’s site search returned its results as a web page. In order to make LearnHub’s site-wide search’s results page have the same look and feel as the rest of the site, they had to stick the Google results in an iframe. “And even then, what was inside the iframe didn’t match the rest of the page,” added John.

They started looking at other options for implementing LearnHub’s site-wide search, including running their own spider. “We really didn’t want to do that,” said programmer Wesley Moxam.

Enter Bing

LearnHub developer Wesley Moxam.

While looking around at search options, Wesley found the Live Search API, which is now known as the Bing API. “It was free, well-designed and spits out JSON,” he said. “Google requires a JavaScript interface or SOAP, and SOAP libraries in Ruby are painful.”

“It took a day to implement and get it up and running,” said Wesley, “The entire switch-over project happened over three days, with us working on it on and off, while we were doing other tasks. Best of all, we get consistent results – the results from the API are the same results you’d get if you just used the Bing site.”

“Bing’s API is simple and straightforward. You call it, you get the results, you take those results and use them how you like,” he continued. “It’s good. It’s hard to explain good software; good software is inherently simple.”

Here’s a screenshot of a LearnHub search results page for the search term “accordion” – and yes, the word appears on a handful of Learnhub pages!

LearnHub’s search results page for the term “accordion”.

LearnHub have benefited from using Bing to power their site-wide search, and they’ve decided to share the wealth. Wesley’s working on refactoring the Ruby library he wrote to act as a wrapper for the Bing API and open source it for anyone to use. It should be available later this summer. He’ll announce it when it’s released, and I’ll announce it here.

The Bing API

It’s easy to harness the power of Bing in your applications, whether for desktop, web or mobile.

The first step is to get an AppID, which is a string that uniquely identifies you as a registered Bing application developer. Go to the Bing Developer Center, sign in with your Windows Live ID (which you can get for free) and follow the link to created a new AppID. You’ll be asked to supply some very basic information about your application and to review the Bing API’s Terms of Use. If you provide the information and agree to the Terms of Use (which I summarize in plain English below), you’ll get an AppID.

Once you have an AppID, you can start experimenting right away with the Bing API. All you need to do is start typing URLs with the format below into your browser’s address bar:

Bing’s Terms of Use, Explained as Simply as Possible

Here’s a quick explanation of Bing’s Terms of Use for those of us without a law degree. It’s adapted from the Bing documentation and provides a quick summary of what application developers using the Bing API must do and cannot do (besides the obvious "I promise not to use the API to plan a terrorist attack, run a drug smuggling ring or help the band Nickelback take forceful despotic rule of planet Earth").

What you must do:

You must display all the results you request. No filtering!

You must display your results in the context of a user-facing application or website.

You must display attribution to Bing in a manner compliant with our branding rules. Currently, you may determine the specific manner in which you display attribution. A link to http://www.live.com with the query echo is a suggested example.

You must restrict your usage to less than 7 queries per second per IP address. You may be permitted to exceed this limit under some conditions, but this must be approved through discussion with the folks at api_tou@microsoft.com.

If you interleave data from any source other than the API with data from the API, you must clearly

differentiate the respective sources. (Yes, you can interleave Bing results with other data!)

What you cannot do:

You cannot use API results for search engine optimization (SEO). In particular, using the API for rank checks is explicitly prohibited.

You cannot display advertisements in positions other than the mainline and sidebar.

You cannot change the order of the results the API returns from a SourceType other than Web. (In other words, you can re-order results from standard searches for web pages!)

Bing Your Apps!

From there, the sky’s the limit. The Bing API is very straightforward and easy to use, it costs nothing to use it, and as someone who’s been using Bing as his default search engine since its beta period, the results it provides are great. Go forth and Bing your apps!

One of the pillars of the Toronto developer scene is the Ruby/Rails community. They’re an active, engaged, hard-working bunch who work without the direct benefit of a large organization like The Empire or its resources (they do, through people like Yours Truly and Nik Garkusha, Microsoft Canada’s open source go-to guy, get some indirect support). They – through the efforts of people like Pete Forde and the Ruby local heroes at Unspace – know how to maximize grassroots organization and harness them into industry-leading events like last year’s RubyFringe and the upcoming FutureRuby conference.

It should therefore not be a surprise that when Pete and company got the idea to help out their fellow Ruby developers during the econopocalypse with a job fair – employment.nil? — they’d take the standard techie job fair formula, turn it upside down and make it their very own. They chose the Gladstone Hotel in Toronto’s hip West Queen West neighbourhood, which is better known as a venue for karaoke, rock bands and burlesque (in fact, I’ve performed in all three kinds of shows there) than for computer and IT-related employment fairs.

This was not your typical job fair. It didn’t have any of the fancy display stands that you normally see on the exhibition floor at tech conferences. Instead, both job-seekers and small companies were told to build poster board displays, a la high school science fairs.

Another rule: no computers allowed! Even iPhone apps were considered “cheating”. The closest you were allowed to get was using whiteboards or pen and paper for “live coding”. This wasn’t about staring at computer screens, but people talking to other people – people who were passionate about the Ruby programming language and its associated frameworks, libraries and communities.

Let’s face it: it’s better to be a Ruby developer than a car manufacturer in 2009, but things have definitely slowed down — for everyone. And yet, there are solid reasons why this is an excellent time to start new projects, launch companies, and create new markets. By definition, Ruby has been adopted by creative individuals that grew frustrated with risk averse bureaucracies.

We believe that there are huge number of opportunities to be found during this economic downturn, both for freelance developers and aspiring entrepreneurs alike. As with most tragic historical near-misses, there are just a huge number of connections that aren’t made even in our own collective back yard.

More from the job fair’s site:

That said, we also believe that Ruby people are determined self-starters that aren’t afraid to self-promote. Anything worth doing in life requires hard work and sacrifice. Sadly, while many developers are patient and willing to think orthogonally, we rarely get an opportunity to practice the other more social skills which make us desirable as team members, project managers, and co-founders. Unless we overcome our shyness and learn to speak eloquently about our experience and skill sets, we have nobody to blame for our work prospects but ourselves.

Our solution is to gather students, developers, development companies, and of course project leaders and company founders for a good old-fashioned career fair.

As you can see from the photos, there were different kinds of booths set up. There were those for companies looking to hire some Ruby developers…

and those deidicated to showcasing some interesting application of Ruby, such as lojacking iPhones:

And some booths were set up by Ruby programmers showcasing their own work and who were looking for a job:

The event wasn’t just noticed by the Ruby community, who filled the room throughout the 11 a.m. to 6 p.m. course of the event. Late in the afternoon, Ontario’s Minister of Small Business and Consumer Services, Harinder S. Takhar, paid a visit to the job fair.

Pete, ever the gracious event curator, took Mr. Takhar to several booths, introducing him to their owners, who were only too happy to show the Minister their Ruby-related work. Here’s Andrew Burke of Shindig, showing him the projects he’s taking on in his independent software consultancy:

I’m sure that grassroots high-tech events with a strong “indie” aesthetic are outside the Minister’s everyday experience, but he seemed pretty impressed with the event: a dedicated group of nerds building software and careers using only laptops, stuff you can download for free and their brain cells.

Here’s Pete explaining the local Ruby developer scene and the concept of open source software to Mr. Takhar:

And here’s Mr. Takhar presenting Pete with an award of recognition for Unspace for putting the event together. At that point, I broke out the accordion and played For He’s a Jolly Good Fellow, partly for the Minister for showing up on a Saturday afternoon, but partly for Pete for putting the event together.

Here’s a close-up of the award:

It reads:

Award of Recognition

On behalf of the Government of Ontario, I am delight to extend my congratulations on the Employment.nil? First Toronto Ruby Job Fair

Unspace Interactive Inc.

Our government recognizes the importance of new and creative opportunities for business. Building a business requires vision and dedication. I applaud your work and success in web consulting through your team of industry-leading developers and designers under one roof.

Please accept my best wishes for continued success.

Harinder S. Takhar Minister of Small Business and Consumer Services June 06, 2009

Congratulations to Pete, Meghann Millard, all the folks from Unspace and the Toronto Ruby community on a job well done!

The merger is commemorated on a “plaque” page on the Rails site titled The Day Merb Joined Rails, which I’ve excerpted below:

Merb was started two years ago by Ezra Zygmuntowicz as a tiny framework to serve ERb templates from Mongrel. This quickly grew into much more and carved out a niche as an alternative Rails stack. Merbists focused on among other things a small speedy core, being ORM/JavaScript agnostic, and having a rigorous API for extensions.

Along with the expansion in ambition came the fact that Merb and Rails started sharing more and more of the same ideas and even implementation. This lead to a fair amount of unnecessary duplication on both sides of the fence and lead to some paradox of choice. When do I choose one over the other and when?

Rails 3

On December 23rd, we decided to end the duplication and the paradox of choice. That was the day we declared our intentions of bringing the best ideas of Merb into Rails 3. That was the day weannouncedourcommitmentto work together.

It’s a win for both projects, as well as the users. Rails gets some much-needed optimization, the ability to shed excess weight for speed, framework agnosticism and an API that won’t break with upgrades, and Merb gets a much bigger development community and mindshare momentum that Rails enjoys. Better still, the merger now has both teams’ big brains working on the same project, and isn’t that what the spirit of the DRY principle is all about?

Congratulations to both the Merb and Rails teams! And hey, congrats to all you Ruby/Rails/Merb developers out there too! 2009 just got a little more interesting for all of us.
